Jeremy,
Different issues....
The patch addresses only 1 topic - making an attribute to change the
timeout for the TMF. This was a request by the distros to post a hack
that was used on older releases to work around all the serialization and
delay problems in the midlayer error recovery path - which allowed
shortening delays from 10-12 minutes to 1-2 minutes. These are the same
issues we discussed at the last storage forum and which Hannes has been
working to correct upstream. The desire is to continue with a like
tuning option in the driver for those customers that have used it in the
past.
The other issue - we seem to have missed your prior post. I'll look into
it shortly.
The two patches work on the same code, but are independent topics.

Fixed issue of task management commands having a fixed timeout
I'm surprised about this change, since it appears a number of issues in the
send_taskmgmt() still exist that keep it from handling task management
failures correctly. It also continues to have a number of smaller issues like
for example dead code of the form
if (status != IOCB_STATUS)
else if (status == IOCB_BUSY)
else
See patch:
"lpfc should check return status for task mgmt IOCB"
